89H48H12G2ZDBLG

Overview

The 89H48H12G2ZDBLG is a specialized PCI Express switch integrated circuit manufactured by Renesas Electronics Corporation. It provides 48 PCIe Gen2 lanes and 12 switch ports, utilizing a non-blocking architecture optimized for high-performance system interconnects. The device supports partitionable switch architecture for true multi-root support and includes internal buffering with flow control credits to maximize bandwidth and handle large payloads. Designed for low latency and low power consumption, it ensures full line-rate throughput for multiple traffic flows regardless of switch loading. The component is housed in a 676-FCBGA package measuring 27x27 mm and operates on a 3.3V supply voltage.

Procurement Notes

This component is officially listed as obsolete or end-of-life. Verification of current availability requires checking authorized distributors for remaining stock or approved replacement alternatives. Ensure the specific suffix matches the required package and temperature grade, as ordering suffixes may indicate variations in manufacturing site or labeling but do not alter functional specifications unless explicitly documented.

Selection Notes

Select this component when designing systems requiring 48 PCIe Gen2 lanes with deterministic, non-blocking switching performance. It is suitable for applications needing partitionable architectures for multi-root support. Verify that the host system can accommodate the 676-FCBGA package size and that the design supports the required 3.3V power supply and thermal dissipation characteristics for surface-mount installation.
